The sequence of the mouse genome is a key informational tool for understanding the contents of the human genome and a key experimental tool for biomedical research. Here, we report the results of an international collaboration to produce a high-quality draft sequence of the mouse genome. Read more

Many human genetic disorders result from unbalanced chromosomal abnormalities, in which there is net gain or loss of genetic material. Traditionally, cytologists have detected such abnormalities by generating a karyotype of a person's chromosomes and analyzing the banding patterns therein. Indeed, since its development in the 1970s, cytogenetic analysis of banding patterns has been the primary tool for the clinical assessment of patients with a variety of congenital anomalies. Under ideal conditions, aberrations as small as approximately 5 megabases (Mb) can be detected with banding analysis; such chromosome rearrangements are termed "microscopic." Read more

The Cancer Genome Atlas (TCGA) Research Network has profiled and analyzed large numbers of human tumors to discover molecular aberrations at the DNA, RNA, protein and epigenetic levels. The resulting rich data provide a major opportunity to develop an integrated picture of commonalities, differences and emergent themes across tumor lineages.
